Modifying Events

To modify an event:
1.
Select the event you want to modify.

2. Press the Change Event button.

Markers a, A, B, and b appear on the graph. With these markers, you
can define a new location for the selected event.

You can reposition all markers directly by dragging them, or by pressing
where you want to relocate them on the graph. Selecting marker A or B
will move the a-A or B-b pair.

Note: The current marker locations are set, during the analysis, to calculate and

display the original event loss and reflectance.
